Meanwhile, at least two Mueller investigators’ past legal work for Clinton-tied figures is getting a second look as Republicans hunt for signs of bias.

Aaron Zebley, another former partner at WilmerHale and a former chief of staff to Mueller when he served as FBI director, represented Justin Cooper, a key figure in the Hillary Clinton email controversy.

Cooper is the longtime Bill Clinton aide responsible for helping set up the now-infamous private email server. Cooper later admitted to “two instances where he destroyed [Hillary] Clinton’s old mobile devices by breaking them in half or hitting them with a hammer.”
